Propelling wind energy innovation

LIVERMORE, Calif. — Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers developed a fundamentally new type of rotary electrical contact. Sandia is now ready to partner with the renewable energy industry to develop the next generation of direct-drive wind turbines. Sandia’s Twistact technology takes a […]

Back to the drawing board: Reinventing offshore wind turbines

ALBUQUERQUE, N.M. — Brandon Ennis, Sandia National Laboratories’ offshore wind technical lead, had a radically new idea for offshore wind turbines: instead of a tall, unwieldy tower with blades at the top, he imagined a towerless turbine with blades pulled taut like a bow. This design would allow the massive generator that creates electricity from […]

“We’ve Got the Power”: Sandia technology test delivers electricity to the grid

ALBUQUERQUE, N.M. — For the first time, Sandia National Laboratories researchers delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. The Brayton cycle is named after 19th […]

20th anniversary of Sandia tribal energy internship program

ALBUQUERQUE, N.M. — 2022 marks a major milestone for Sandia National Laboratories’ groundbreaking tribal energy internship program: two decades of meeting the growing renewable energy technical needs of Native American tribes and providing valuable, real-world experience for Native and Alaska Native STEM students. “My hope for the interns is for them to be leaders in […]

Using the power of the sun to roast green chile

ALBUQUERQUE, N.M. — Every August and September the unmistakable pungent aroma of roasting green chile permeates the air across New Mexico and neighboring states. This delectable staple of regional cuisine is green in color, but roasting the chile pepper to deepen the flavor and make the inedible skin easier to remove is hardly environmentally friendly. […]

Exploring explosives for expanding geothermal energy

ALBUQUERQUE, N.M. — Why are scientists setting off small-scale explosions inside 1-foot cubes of plexiglass? They’re watching how fractures form and grow in a rock-like substance to see if explosives or propellants, similar to jet fuel, can connect geothermal wells in a predictable manner. Geothermal energy has a lot of promise as a renewable energy […]

Sandia creates global archive of historical renewable energy documents

ALBUQUERQUE, N.M. — Sandia National Laboratories began studying the power of the sun to produce utility-scale energy in the 1960s. Sandia’s National Solar Thermal Test Facility was commissioned in 1978, spurred by the oil crisis of 1973. Many of the documents detailing the design, construction and research conducted at the world’s first multimegawatt concentrating solar […]

High-speed alloy creation might revolutionize hydrogen’s future

LIVERMORE, Calif. — A Sandia National Laboratories team of materials scientists and computer scientists, with some international collaborators, have spent more than a year creating 12 new alloys — and modeling hundreds more — that demonstrate how machine learning can help accelerate the future of hydrogen energy by making it easier to create hydrogen infrastructure […]

Sandia uncovers hidden factors that affect solar farms during severe weather

ALBUQUERQUE, N.M. — Sandia National Laboratories researchers combined large sets of real-world solar data and advanced machine learning to study the impacts of severe weather on U.S. solar farms, and sort out what factors affect energy generation. Their results were published earlier this month in the scientific journal Applied Energy. Hurricanes, blizzards, hailstorms and wildfires […]

Sandia designs better batteries for grid-scale energy storage

ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories have designed a new class of molten sodium batteries for grid-scale energy storage. The new battery design was shared in a paper published today in the scientific journal Cell Reports Physical Science. Molten sodium batteries have been used for many years to store energy from renewable sources, […]

Sandia-led center to advance understanding of new solar panel technology

ALBUQUERQUE, N.M. — The Department of Energy recently awarded $14 million to form a Sandia National Laboratories-led center to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels’ lifetimes. The efficiency of perovskite-based solar cells has reached 25%, approaching the levels of common crystalline silicon-based solar […]

Here comes the sun: Tethered-balloon tests ensure safety of new solar-power technology

ALBUQUERQUE, N.M. — What do tiny dust particles, 22-foot-wide red balloons and “concentrated” sunlight have in common? Researchers from Sandia National Laboratories recently used 22-foot-wide tethered balloons to collect samples of airborne dust particles to ensure the safety of an emerging solar-power technology. The study determined that the dust created by the new technology is […]
